Hi all
There is no difference, except that I have only ever found them in Spain. There is a good selection of colours so its a way to categorize them. The shield is a bit bigger than many baby dummies (pacifiers) so it goes well with the Nuk4 or Nuk5 teat. Also they have a cute matching keeper clip in the shape of a teddy which with the lengthened ribbon is popular with ABs or the older paci user.
